Change the behaviour of `-v' so that, e.g., stepping a month back

on March 31 won't take you to March 2 or 3 (now the result will be the last day of February.) In general, now stepping by months from the last days of the current month A will take you to the very last day of the target month B if B is shorter than A. The previous version would just step to March 31 and rely on mktime(3) to correct the date. Despite its simplicity, such way was counter-intuitive to users and caused pain to shell script writers.

Give the most awesome example of how to parse the output of date

back into epoch time. Everytime I'm asked to do this by someone I have to spend about ten minutes recreating the same command line. So record it under examples.

Deal with double whitespace.

Mechanically kill hard sentence breaks.

DESCRIPTION was not updated for the new SYNOPSIS.

Give date(1) a much better SYNOPSIS section which is useful as more than

2004-04-06T22:03:38Z

decoration. Further improvements are welcome, but at least this is a separate of the various modes of operation date has, as well as sectioning off the two deprecated options for settimeofday(tz) that don't even apply to actual operation of date as such, anyway.

Remove clause 3 from the UCB licenses.

Rev. 1.32 moved a comment to the wrong line. The hack refered to

2004-03-04T15:46:14Z

in the comment applies to a decision that needs to be made in relation to the year 2000. In fact, that statement probably should be changed to be more generic (getting the year from the current time perhaps). Otherwise, starting in 2069 two digit year conversions in date(1) will start assuming 1900 instead of 2000. hehe.

Note the Linux required format.
